The organization over time
Each line starts at 100 in 2018, so what you read is the shape rather than the size: 150 means half as much again as 2018, 50 means half. The number beside each label in the key is where it ended.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2024 to 2025, from $1.0M to $0 (−100%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2021 12% · 2022 5% · 2024 2% · 2025 68%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 8 reported years ran a deficit.

Who funds it, year by year
2018 → 2023: the base broadened from 1 funder to 5 funders, grant income rose $100k → $575k.
1 of 11 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 13% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of MASTERY TRANSCRIPT CONSORTIUM’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
MASTERY TRANSCRIPT CONSORTIUM has a broad base — no single funder exceeds 25% of grant income, and it takes 3 funders to reach half.
the vertical line marks half of all grant income — 3 funders to its left
40% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund MASTERY TRANSCRIPT CONSORTIUM.
Largest funder’s share by year: 2018 100% · 2020 100% · 2021 60% · 2022 52% · 2023 35% — diversifying over time.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
0% of MASTERY TRANSCRIPT CONSORTIUM's funders are still giving 2 years after their first grant; 9% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
MASTERY TRANSCRIPT CONSORTIUM draws 86% of its grant income from funders outside Massachusetts, across 6 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $250k arriving through sponsors registered in 1 state is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
